MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent, No. 373,317, dated November 15, 1887.

Application tiled January 13, 1887.

To aZZ- whom, it may concern.-

Be it known that I, J onN HENRY SMALLl WoOD,a subject of the Queenv of Great Britain, residing at Paterson, in the county of Passaic and State of New Jersey, have invented new and useful Improvements inMechanical Movements, of which the following is a specification.

This invention relates to an improvement in mechanicalmovernents, as set forth in the following specification and claims vand illustrated iu the accompanying drawings, in which* Figure l is a front elevation, partly in section, of avmechanical movement. Fig. 2 is a side elevation ot' the same.

Similar letters indicate corresponding parts.

The arrows shown in the drawings indicate the direction of movement of the vparts at one moment.

Ais afi-ame or support,of wood,iron, or anyA suitable material.

B is a reciprocating actuator operating in a. guide-frame, C. Motion is imparted to the re! ciprocating actuator by suitable means-such, for example, as a rod or pitman, D, connected by suitable means-such'as a pivot,W-to the actuator B. A crank, E, mounted on a shaft, F, and connected by a pivot, G, with the pitman D, imparts motion to the latter, and thereby reciprocates the actuator B, said actuator, as here shown, consisting of a sliding bar. To the upper and lower portions, respectively, of the actuatorare attached the ends of two straps or chains, J K, which extend toward each other and then pass over guidessuch as pulleysL-and'are connected to cords or chains VM and S as follows: The cord or chain M passes Serial No. 224,226. (No model.)

consequently the cords or chains M S are moved and the pulleys N and V thereby oscillated in opposite directions, as indicated by the arrows, Fig. l, this being permitted by reason of the strap K moving in thedirection of the arrow' adjacent to said strap. The downward movement of the actuator necessarily oscillates thepulleys in the opposite directions, and such oscillating movements impart alternating motionsto the beams Q R.

The pulley N, as shown in Fig. 2, is coneshaped, so that by placing the chain M about different diameters of said pulley the latter can be oscillated with greater or less speed.

As an example of applying my invention, I will mention that the rods or beamsQ R can be part of the heddle-frames of a loom harness, the alternate movements of the beams actuating the heddles to form sheds for the fabric being woven,as usual. The heddle -fra-mes can be depressed by springs 1 2, or otherwise. .I do not, however, confine my invention to the special purpose alluded to.

Vliat I claim as new, and desire to secure by Letters Patent, isn l. The combination of a main frame, A, a vertical guide-frame,C, the reciprocating actuator B in the guide frame, the two straps or chainsJ K, connected,rcspectively, with the upper and lower portions ofthe actuator, guidepulleys L on the guide-frame for the straps or chains,the pulleys Nand Von the main frame, cords or chains O P and T U, respectively connecting the latter pulleys with the object to be operated, and cords or chains M and S, passed, respectively, around the pulleys N and V, and each chain having one end secured to the strap J and the other end secured to the strap K, for

oscillating the two pulleys in opposite directions, substantially as described.

2. The combination of a frame, A, the reciprocating actuator B, the two straps or chains J K, connected, respectively, with the upper and lower portions of the actuator, guides L for the straps or chains, the pulleys N and V In testimony whereof I have hereunto set on the frame, and cords or chains M and S,

my hand and Seal in the presence of two subpassing, respectively, around the pulleys, and scribing Witnesses. each strap having one end secured bo the strap JOHN HENRY SMALIAVOOD. U.. sx] 5 J and the other end secured to the strapl, for

oscillating the two pulleys in opposite diree tions, substantially as described.
